Background: Glutaric aciduria type II is a rare disorder affecting the metabolism of fatty acid oxidation and several mitochondrial dehydrogenase enzymes. Narcolepsy and cataplexy is a disorder affecting sleep cycles and rapid eye movement activity. There is little information on outcome or management for either disorder in pregnancy.
Case: This is a case of a 16-year-old with glutaric aciduria type II and narcolepsy with cataplexy, treated with L-carnitine, riboflavin, fluoxetine, and modafinil during pregnancy. Intrapartum management included intravenous carnitine administration, and the patient underwent cesarean delivery at term without complication.
Conclusion: This inborn error of metabolism and sleep disorder can be effectively treated during pregnancy with nutritional supplementation and stimulants. Because of the risk of cataplexy during labor, cesarean delivery is recommended to minimize the patient's risk.

Glutaric aciduria type 1 (GA1) is a rare inherited metabolic disease increasingly included in newborn screening (NBS) programs worldwide. Because of the broad biochemical spectrum of individuals with GA1 and the lack of reliable second-tier strategies, NBS for GA1 is still confronted with a high rate of false positives. In this study, we aim to increase the specificity of NBS for GA1 and, hence, to reduce the rate of false positives through machine learning methods.

Lysine metabolism converges at α-aminoadipic semialdehyde dehydrogenase (ALDH7A1). Rare loss-of-function mutations in ALDH7A1 cause a toxic accumulation of lysine catabolites, including piperideine-6-carboxylate (P6C), that are thought to cause fatal seizures in children unless strictly managed with dietary lysine reduction. In this study, we perform metabolomics and expression analysis of tissues from Aldh7a1-deficient mice, which reveal tissue-specific differences in lysine metabolism and other metabolic pathways.

Unlabelled: Glutaric aciduria type 1 (GA1) is a rare metabolic disorder characterized by a deficiency in the enzyme glutaryl-CoA dehydrogenase. This study aims to present the clinical, biochemical, genetic, and neuroimaging findings of GA1 patients, emphasizing the importance of early detection and the potential benefits of incorporating GA1 into NBS programs. The demographic, clinical, and laboratory findings of GA1 patients were reviewed retrospectively.

The biochemical hallmark of D-2-hydroxyglutaric aciduria is brain accumulation of D-2-hydroxyglutaric acid (D2HG). Patients present predominantly neurological manifestations, whose pathogenesis is still unknown. Thus, we examined the impact of elevated brain levels of D2HG, induced by intracerebral injection of this metabolite in juvenile rats, on redox and mitochondrial homeostasis and histochemical landmarks in the cerebral cortex.
